Many of you may remember the interview we held with Potion Factory's founders in October about a new software app they were working on called Tangerine. For those who need a reminder, Tangerine! is an app that analyzes the BPM and intensity of your music to create automatic playlists, based on your preferences, within a certain beat and intensity range—awesome for use with Nike+iPod, or working out in general.

Since then, they've changed the name to "Tangerine!" (in an attempt to avert name confusion with another software package) and added lots of new things to the software.

Today, they released Tangerine! into version 1.0 and it's officially on sale as a full release. Congratulations to Jin and Andy Kim. Ever since we interviewed them last, they added a whole bunch of stuff, including:

The ability to see purchased iTunes songs (you have to set the BPM yourself by hitting ?-D)

Version 1.0 is just 1.6MB and requires OS X 10.4. The full version costs $24.95, but there is also a 15-day free trial. I can tell you from personal experience that I think this software is awesome, especially for working out, but according to Potion Factory's press release, people have been using it for all sorts of stuff:

While the original intent of the developers was to have the software pick out songs to exercise to, many of the early testers have made playlists for various kinds of activities with Tangerine!, such as: falling asleep, dancing, or even vacuuming. Some have even created playlists to help them get into the zone while programming while others claim that Tangerine! will drastically change the way they enjoy their music.

Hmm, it never occurred to me to create a vacuuming playlist, although I have been known to create playlists for doing the dishes. Maybe these people are on to something...
